These are in no specific order.
Goat’s Milk which has been said by the National Institutes of Health is easier to digest than cow’s milk but is higher in calories than 2% milk. This milk may not be good for lactose intolerance individuals. It can be found in Health Food Stores and some supermarkets.
Almond Milk has 40 to 100 calories per 8 oz. serving and has half the fat as 2% milk. I tried Silk and Blue Diamond and they were both good. You can find it in the Supermarket.
Rice Milk is said to be great for people who are lactose intolerant. It is about 120 calories per 8 oz serving. Unsweetened rice milk has more carbohydrates than regular milk. I only tried the chocolate flavored and it was okay. This can also be found in the Supermarket.
Hemp Milk is made much like almond milk Its consistency is that of rice or soy milk. The one thing with hemp milk is it has a grittiness to it and not everyone likes it. It is fortified with naturally occurring omega-3s and 6s and good amount of essential amino acids. I haven't tasted it so I can not say how it tastes. i'm not sure where it is sold; I would think in the health food stores.
Coconut Milk Yummy and are only about 60 calories per 8 ounce serving. That's 1/2 the calories of 2% milk. You can buy this is the Supermarket.
Well, that's my list of milk substitutes. If you have any to add to this list - let me know.
Have a great day!
